Application filed October 29, 1921. Serial 'No'; 511,324. I

To all whom dimer concern: I

Be it known that I, Ti-rnonoRnCoiri ron, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Excavator 1nd. Loader, of whichthe following is a specification.

This invention relates to combined ex cavating and loading devices, the primary object of the invention being'to provide means for moving .a scoop to aposition where the contents thereof may be readily and easily discharged to 'load the contents into a vehicle, of the usual'construction.

Another object of the invention is to provide a carriage to receive the scoop and'support the'weight of the scoop and its contents while the same is being moved to a dumping position.

A further object of the invention is the provision ot-means'to operate the carriage and scoop, to the upper end of the device.

lVith the toregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction"hereinafter described and claimed, it being understood that changes in'the precise embodiment of the invention herein disclosed, may bemade within the scope of whatis claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 a perspectiveview of a device constructed in accordance with the present invention, and-illustrating the scoop and,

carrier in their dumping positions.

Figure 2 IS a front elevational new of a scoop the carrier being shown 1n section.

Figure 3 is an enlarged detail view dis-' closing the means used for connecting the scoop to the carrier.

Figure 4 is an enlarged detail view disclosing the rollers and their connection with the inclined track-way.

Referring to the drawings in detail, the device includes a support or body portion indicated generally by the reference character 5, which body portion is supported by means of the axle 6 and wheels 7 and 8.

The axle 6 is secured to the beam 9, which is shown as extending transversely of the body and provides the main support for the body, suitable bands 10 being provided to whereby the same may be moved se cure'the axle '6 to the beam 9. At the forwardend of theqdevice arethe vertically disposed spaced angle irons 11 which'are braced, and heldin their proper spaced relation,.,by means of the angularly disposed bars 12, a bar 13 being provided to connect j the angle irons 11' at their upper ends.v

Supported by: these angle irons 11 at a point substantially intermediate the ends thereof, .is a loading hopper '14, which is formed with a. discharge'spout at the lower end thereof, the discharge spout being con.- trolled 'bv the hinged door 15, "which may be opened and closed at the'willot the op-' erator to accomplishing the loading of a vehicle, which is moved the spout.-

A laterally extending frame including-the arms l6 a'ndbar 17,;is disposed adj acent to the upper end-of the angle irons 11 and supports the pulleys 18over which the operat'-' ing' cahlejl9 "moves to accomplish the moving of the carrier-and scoop to'a'dumping position- This cable l9 is"shown as-con-. nected to thescoop 20 as by means of the to a position under chain sections 21Lthe'lcable passing from the innermost pulley 18 over the-pulIeyQ-Q.

which is disposed'adjacent-to the body of the device, the cable passing to thedrum 23 which is supported by'the' body as clearly shown by Figure 1 "of thedrawing.

Associated with the drum 23 is afdrum 24- on which the cable 25 is wound,when-'the carrier andscoop are moved totheir-lowermostzpositions, andlsince the drums 23iand 24 are mounted on the same shaft and the cables 10 and 25 are oppositely wound on their respective drums, it is obvious that upon movement of one drum in one direction to wind its cablethereon, the cableon the opposite drum is unwound.

As shown, the cable 25 passes over the pulleys 26 from where the same pa'ssespto the date the laterally extending arms 30 form ing a partof the scoop proper.

The vertically disposed angle irons 11 are also braced'by meansof the inclined trackoperating the drums 23 and2 l,

ways 31 which are connected to the body adjacent to the lower ends thereof, the upper ends of the trackways extending inwardly and downwardly towardsthe hopper 14 so that the carrier will be directed downwardly to discharge the load of the scoop, directly into the hopper.

Pairs of rollers indicated at 32 are carried adjacent to the forward end of the scoop and engage under the trackway, while the rollers 33 which are supported-adjacent to the rear end ofthe scoop contact with the tread'portion of the trackwayf Thus it will be seen that the carrier is held to the tractway, and properly tilted -when the same reaches the limit of its upward movement.

In order that the inclined trackway 31 will be held in its proper inclined position, bracingbars 34 are provided, which also extend forwardly-andconnect with the hopper 14' as shown at 85. The rails 36 which form the trackway 31 are held in proper spaced relation by means of the spacing bars 37. 7

It might be further stated that a suitable power device, such as an internal combustion engine indicated at 38, may be employed for operation of the device. 7

I In the operation of the device, the scoop is moved through the earth, by means oi": the cable 19, whereupon the same is directed to the carrier: 27, which in its normal position, is'held adjacent to the lower end of the trackwa The scoop now pas'ses onto the carrier ,where the-laterally. extending arms 80 contact with'the members-29 to connect the scoo to the carrier.

" Itfollows that upon-further movement of the cable 19, which is now being wound on the drum 28;, the scoopand carrier together with the contents of the scoop are moved to a position :as' indica'tedby Figure 1 of the V drawings, -where the same discharges its load into the hopper v14E. -As the hopper 14L becomes filled, the closure 15 may be operto cause the ated to allow material to discharge from the hopper and into a suitable conveyor or vehicle. c

Having thus described the invention, what is claimed as new is':

1. In a combined excavator and loading machine, a wheel supported body portion, an inclined track having'its upper end terminatingat a point above the body portion, a

hopper disposed adjacent to the upperv end of the inclined track, a carrier having rollers and adapted to move over the track, said carrierhaving upwardly extending arms, a scoop adapted to move onto the carrier, laterally extending arms on the scoop'and adapted to engage the upwardly extending arms of the carrier for connecting the scoop and carrier, meansihaving connection with the scoop for moving the'scoop andcarrier over the-track, and said arms of the scoop adapted to disengage the arms of the carrier when the scoop is moved to its ,loadino' position.

2. In a combined'excavator and loading machine,"a body portion, a frame supported by the body portion, a hopper supported by the frame, an inclined track supported by 'the'body portion and having a right angled upper end portion overlying one end of the hopper, a carrier movable over the'track section, a scoop adapted to move wlthinthe carrier, means secured to the carrier and contacting with the ,scoop for movingthe carrier over the track with the scoop, means for moving thescoop to the right angled port-ion of. the track where the same may dump its contents into the hopper, and means
